I wonder if someone in WRI could shed some light on the reason that
allegedly made this a bug only on Pentiums and not on AMD's processors. Was
the code detecting the CPU type and using the SSE instructions (faster but
with lower internal precision w.r.t. the 80 bit x87 FPU operations)?
I am insolently curious. : )
